Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a spraying waste gas treatment device. Background Technology
[0002] During plasma spraying, some raw materials evaporate and generate waste gas when they reach a high-temperature molten state. To prevent the evaporating waste gas from harming the surrounding environment and workers, a spraying waste gas treatment device is usually used to treat the waste gas emitted during plasma spraying. Existing spraying waste gas treatment devices typically consist of a spray treatment box, an activated carbon filter, and a waste gas recovery mechanism. Currently, traditional spraying waste gas treatment devices contain a large amount of particulate matter in the evaporating waste gas from plasma spraying. These particles adhere to the activated carbon filter when passing through it. However, over a long period of use, the accumulation of particles adhering to the activated carbon filter can easily clog the filter, affecting the effectiveness of the spraying waste gas treatment and making it inconvenient to use.
[0003] Chinese patent CN222918425U relates to the field of metal surface treatment technology and discloses a device for treating exhaust gas from angle steel spraying. The device includes a housing, a purification chamber, and a drive motor. A mounting frame is fixed inside the purification chamber, and multiple support rods are mounted on the mounting frame. A loading frame is mounted on each support rod, and the loading frame is connected to the mounting frame via a first return spring. Multiple fixing components are mounted on the loading frame, and multiple condensing plates are fixedly mounted on the fixing components. The housing includes a screening chamber and a treatment chamber, and the filter plate is rotatably connected inside the treatment chamber. A collar is coaxially arranged on the filter plate, and a connecting component is installed inside the collar. Shafts are provided at both ends and the center of the connecting component. This utility model uses fixing components to install multiple condensing plates, and the special shape design of the condensing plates allows for a longer contact time between the exhaust gas and the condensing plates, thus causing water vapor in the exhaust gas to condense. However, this utility model cannot easily and promptly replace the cleaning components, nor can it adjust the number of absorption components according to actual conditions, and it lacks a multi-filtration effect, requiring improvement.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0021] Please see Figure 1-4 An embodiment of this utility model provides: a spraying exhaust gas treatment device, including an air inlet pipe 1, an outer housing 2 fixedly connected to the side of the air inlet pipe 1, an air inlet assembly 3 installed inside the air inlet pipe 1, a main treatment chamber 4 connected to the side of the air inlet pipe 1, the main treatment chamber 4 fixedly connected to the outer housing 2, a post-treatment chamber 5 fixedly connected to the side of the main treatment chamber 4, a support plate 6 fixedly installed at the bottom of the post-treatment chamber 5, the bottom of the support plate 6 fixedly connected to the outer housing 2, and an air outlet 7 fixedly installed on the side of the post-treatment chamber 5;
[0022] Based on the above structural features, exhaust gas is drawn in through the intake pipe 1, pre-treated by the intake assembly 3, and then sent to the main treatment chamber 4 in the outer casing 2. The main treatment chamber 4 treats the gas, and then sends the gas to the post-treatment chamber 5 for further treatment. The bottom of the post-treatment chamber 5 is supported by a support plate 6, and the exhaust pipe 7 discharges the gas.
[0023] Please see Figure 1 and Figure 2 The air intake assembly 3 includes a back plate 31, an air intake motor 32 is fixedly installed on the back plate 31, a turbulence fan 33 is installed on the air intake motor 32, a dehumidification assembly 34 is provided on the side of the turbulence fan 33, and the dehumidification assembly 34 is fixedly connected to the air intake pipe 1.
[0024] Please see Figure 1 and Figure 2 The dehumidification component 34 includes a condenser plate 341, a collection tank 342 is installed on the side bottom plate of the condenser plate 341, and a water collection chamber 343 is fixedly installed at the bottom of the collection tank 342.
[0025] Based on the above structural features, when this device is in use, the intake motor 32 on the intake assembly 3 drives the turbulence fan 33 to rotate and draw in the exhaust gas, and fully turbulent the exhaust gas. The dehumidification assembly 34 performs a pre-dehumidification operation on the gas. The condenser plate 341 condenses the moisture in the exhaust gas and collects it in the collection tank 342. The water is then sent from the collection tank 342 to the water collection chamber 343 to complete the pretreatment.
[0026] Please see Figure 1 and Figure 3 The main processing chamber 4 includes a chamber wall 41, on which a partition 42 is fixedly installed. Multiple sets of partitions 42 are evenly installed inside the chamber wall 41. Rotary sealing plates 43 are rotatably installed on the partitions 42. Rotary motors 44 are connected to the side of the rotating sealing plates 43. Multiple sets of rotating motors 44 are connected to the chamber wall 41. A main absorption component 45 is installed between the partitions 42.
[0027] Please see Figure 1 and Figure 3 The main absorbent 45 includes an activated carbon plate 451, which is mounted on a partition 42. A central shaft 452 is mounted on the side of the activated carbon plate 451, and an activated carbon plate 453 is mounted on the side of the central shaft 452.
[0028] Please see Figure 1 and Figure 4 The post-processing chamber 5 includes a rear chamber body 51, on which a metal wire mesh 52 is installed, a polymer filter cotton 53 is installed, and a non-woven fabric 54 is installed.
[0029] Based on the above structural features, after gas pretreatment, it enters the chamber wall 41. Depending on the gas condition, the rotating motor 44 on the side of the chamber wall 41 rotates a different number of rotating sealing plates 43, so that the activated carbon plate 451 inside absorbs the gas. The rotating sealing plates 43 that do not rotate seal the activated carbon plate 451 on their sides. When the activated carbon plate 451 needs to be replaced, the activated carbon plate 453 on the central shaft 452 can be inserted into the chamber wall 41 for use. Then, the activated carbon plate 451 is cleaned. After treatment, the gas is sent into the rear chamber 51, where it is thoroughly cleaned and sent out through three filtration processes: metal wire mesh 52, polymer filter cotton 53, and non-woven fabric 54.
[0030] Working principle: When this device is in use, the intake motor 32 on the intake assembly 3 drives the turbulence fan 33 to rotate, drawing in the exhaust gas and thoroughly agitating it. The dehumidification assembly 34 pre-dehumidifies the gas, and the condenser plate 341 condenses the moisture in the exhaust gas and collects it in the collection tank 342. The water is then sent from the collection tank 342 to the water collection chamber 343, completing the pretreatment. After pretreatment, the gas enters the chamber wall 41. Depending on the gas conditions, the rotating motor 44 on the side of the chamber wall 41 rotates a different number of times. The sealing plate 43 allows the activated carbon plate 451 inside to absorb the gas. The rotating sealing plate 43, which is not rotating, seals the activated carbon plate 451 on its side. When the activated carbon plate 451 needs to be replaced, the activated carbon plate 453 on the central shaft 452 can be inserted into the chamber wall 41 for use. Then, the activated carbon plate 451 is cleaned, and the gas is sent into the rear chamber 51 after treatment. It is then thoroughly cleaned and sent out by three filtration processes: metal wire mesh 52, polymer filter cotton 53, and non-woven fabric 54.
